Data encryption for added security

Three advantages of STARTTLS
Here are three benefits of STARTTLS.
STARTTLS encrypts communications between mail servers to prevent data interception or tampering by third parties. Data on the communication path is encrypted and sent safely to the medical mail list recipient. This strengthens the protection of confidential and personal information and reduces the risk of data leaks and unauthorized access.
No need for a dedicated port number
Another advantage of STARTTLS is that it does not require a dedicated port number. Normally, separate ports must be prepared for encrypted email communication and for unencrypted communication. However, because STARTTLS uses the TLS protocol, it can use the same ports 25 or 587 as SMTP, which supports TLS. This means that there is no need to prepare a separate dedicated port number, and security can be improved simply by changing the existing settings. This makes it easy to build a secure communication environment.
Can send even if the recipient does not support encryption
STARTTLS allows sending even if the recipient does not support encryption. When the sender enables STARTTLS and sends an email, if the recipient supports STARTTLS, the email will be encrypted and sent, but if the recipient does not support STARTTLS, the communication will continue unencrypted. STARTTLS determines whether or not to encrypt according to the specifications of the destination mail server, and email can be sent in either state, allowing for flexible support.
